摘　　要：运用GIS技术对四川省青川县土地利用状况、坡度、降雨、温度和行政区域进行分析。结果表明:青川县需要退耕还林还草的旱地面积为23571hm2,占全县旱地总面积的37.7%,并占该县土地总面积的8.1%;且空间分布广泛,全县31个乡镇均有分布,其中大院、青溪、骑马、苏河、凉水五乡镇的分布相对较多,占全县需要退耕还林总面积的30.6%。With the support of GIS technology,an analysis of land use,slop,temperature,precipitation and districts of Qingchuan county,Sichuan province has been made. The result shows all the dry land returned to forest or grass land of the studying area is 23571 hm^2.that is 37.4% of the total area of Qingchuan＇s farm land and 8.1%of Qingchuan lande area.Those type of land widely spread in all 31 towns of the county and relatively concentrate in Dayuan,Qingxi,Qima,Suhe and Liangshui.
